They had a couple huge explosions of this sort, and I'm pretty sure loansindi was there to try to put a can on it every time. Funny how he works.
I agree with you that there definitely should be more detailed genres. Like you said, people get so much grief because elitists decide that something deserves a 0 because it's not Heavy Metal, or it's not Hip-Hop. But hey, more that half of NG traffic is 15 and under (not really, I actually have no idea) so most people are going to click the burn-in-a-fire button and not care.
NG's just been doing things that way for so long, and people like Mich and loansindi have been against change for so long that it'd be too much effort to change their minds and get something done about it.
Kudos for standing up, though.
